| Abstract: | The phase change and energy storage microcapsules were prepared by taking PLA as shell and paraffin wax as core.The structure and properties of the microcapsules were analyzed by FTIR,SEM,TGA and DSC.The results show that paraffin wax was successfully encapsulated by PLA,and the particle size of the microcapsules is about 5~10 μm;the thermal stability of the microcapsules improves obviously in a certain temperature range,and there is no mass loss below 300℃;the energy storage of the microcapsules reaches 170.52 J/g. |
